Have unfortunately not had much time to play around with it yet,
just a quick test so far.
The mouse pointer sure moves fast now, almost too fast , like night and day compared to the original Amiga mouse.

Tried to order, but as of now they are out of stock, and should be back in the middle of January .

In English:
Sum adapter allows you to connect a USB keyboard HID Amiga. It is designed to be mounted inside the enclosure Amiga 1200. The design was based on a 16-bit microcontroller from Microchip.

Sum has an internal USB stack enables the handling of USB HID keyboard type without having to install additional software on the Amiga operating system. Installation boils down to the imposition of the adapter plate on the system motherboard U7 Amiga 1200.

Sum adapter has a "bootloader", unique among other adapters for keyboards, which enables software updates.

Hmm, so I take it there's (yet) no support for scrolling with the wheel?

Of course, FreeWheel would probably have to be used additionally but the lowlevel hardware usually needs to support it with a driver somehow (e.g the EZMouse, Cocolino, Micromys adapters have something similar).

We are pleased to announce that we have established cooperation with several online shops for retro computing fans.
In the upcoming days our products should become available from these sellers:

i must say that in addition to a Gotek (with Cortex FW), the two Ryś MKII (which work wonderfully) have given one of my old and trusted A500s a new breath of live. if before i turned the Amiga on about once a month, i'm now turning it on every day. feels like the late 80's again! yay!

thank you all for continuously bringing us new Amiga stuff. i can't wait to see what the future holds. as my revered companion attests, the Amiga is far from dead and partly it's because of you guys. cheers!

I finally updated my Ryś USB HID adapter's firmware (Rys_20150512.hex). The upgrade went without problems on Win10. Optical mouse precision is good. Is the latency slightly bigger now or am I just imagining?

I read that it can also be used the other way - to connect Amiga/Atari joysticks to the PC. Is that accurate? Because I think that could be very useful to be able to use real joysticks in emulation. In that case, I assume a DB9 gender changer is needed?

Here is a diagram of such an adapter. You can also buy the adapter from other producers.
